Title: Combustion device
Inventor: AKUTSU TSUNEO
IPC: F23D3/20
Filed: 1982-03-04
Abstract: PURPOSE:To reduce a raising flame over a combustion cylinder and improve a safety of the combustion device by a method wherein a raising flame prevention body is arranged over the inner flame cylinder. CONSTITUTION:An inner flame cylinder 10, outer flame cylinder 11 and an outer cylinder 12 are constituted substantially in a concentric form with a relative proper clearance thereamong. Fuel gas is supplied from an extremity end of a wick 9 positioned at a lower end of the clearance between the inner flame cyliner 10 and the outer flame cylinder 11. Conbustion air is supplied to the gas from the lower end of the clearance between the outer flame cylinder 11 and the metallic cylinder part 12' and from the interior of the wick guide cylinder 10, and then mixed with the gas. Numeral 13 indicates a raising flame prevention body and its outer circumfrerence is formed to cover a clearance between the inner flame cyliner 10 and the outer flame cylinder 11 up to an outside part thereof. Thus, since the large raising flame is turned outwardly by the raising flame prevention plate 13 to cause the height of the raising flame to be decreased, its mixing with secondary air is improved and an amount of raising flame is reduced and a guite safe operation can be assured.

IPC: B23B5/36
Filed: 1981-03-12
Abstract: PURPOSE:To avoid leaving any uncut portion on the axis of rotation of a workpiece, by providing a servomotor on a main rotary shaft on which a tool is held, to specifically control the radius of rotation of the tool depending on the angle of rotation of the tool to bring the tool into line contact with the generated surface of the workpiece. CONSTITUTION:When a parabola is defined as z=x<2>/4alpha where alpha denotes the focal distance, the angle theta and radius gamma of rotation of a tool 23 are controlled into a relationship defined by a formulaI. Trains of pulses are produced for simultaneous operation along two axes by a numerical controller 40 on the basis of electronic computation according to the formulaI. The train of pulses for the operation along one axis are applied to a servomotor 37 to rotate a main shaft 22 for a tool 23. The other train of pulses are applied to another servomotor 31 to move the tool 23 in the radial direction. The cutting edge of the tool 23 is thus revolved along the parabola. A workpiece W is slowly rotated. As a result, a desired paraboloid of revolution is generated.

Abstract: PURPOSE:To decrease the content of the iron-component in the molten zinc in a duct by providing an electromagnetic inductor in the upper part of a continuous galvanizing cell, installing a refractory pipe in the lower part thereof, and inducing flow in the molten zinc enclosed by the airtight duct. CONSTITUTION:An electromagnetic inductor 8 is provided in the upper part of a galvanizing cell 1 and a refractory pipe 10 having a grooved hole 11 in contact with the lower part thereof is installed. The inductor 8 generates an advancing magnetic field when electricity is supplied thereto. The molten zinc 2 near the other end 13b of a conduit 13 connecting to the hole 11 is attracted by said magnetic field and is discharged through the conduit 12 at the other end into an airtight duct. If the direction of the advancing magnetic field is reversed, the molten zinc 2' in an airtight duct 7 is discharged from the other end 13b of the conduit 13. The molten zinc 2' in the part enclosed by the duct 7 is thus substd. at all times. Even if the iron-component eluting from a steel strip 4 enters the zinc 2' enclosed by the duct 7, the iron-component is dispersed over the entire part of the cell 1.
